我需要在JBOSS EAP 7.0服务器中创建一个Oracle数据源
我使用以下命令从JBOSS管理CLI(命令行界面)部署了ojdbc6.jar
deploy <PATH_TO_ORACLE_DRIVER_JAR>
部署驱动程序后,我可以看到服务器日志如下
01:25:53,338 INFO [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-1) WFLYJCA0018: Started Driver service with driver-name = ojdbc6.jar
01:25:53,747 INFO [org.jboss.as.server] (management-handler-thread - 6) WFLYSRV0010: Deployed "ojdbc6.jar" (runtime-name : "ojdbc6.jar")
但是,当我尝试从Jboss管理控制台创建oracle数据源(oracle.jdbc.driver.OracleDriver作为驱动程序类)时,出现以下错误
01:31:35,084 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 66) WFLYCTL0013: Operation ("add") failed - address: ([

]) - failure description: {"WFLYCTL0180: Services with missing/unavailable dependencies" => [

"org.wildfly.data-source.OracleDS is missing [jboss.jdbc-driver.oracle]"
]}

service jboss.jdbc-driver.oracle (missing) dependents: [service jboss.driver-demander.java:/OracleDS, service org.wildfly.data-source.OracleDS]
1)我可以知道是什么引起了这个问题吗？缺少什么依赖性？
2)将JDBC驱动程序安装为数据源创建的JAR部署是否正确？
解决方法:
将JDBC驱动程序安装为核心模块
>在$JBOSS_HOME / modules下创建目录.在此示例中：“ $JBOSS_HOME / modules / com / oracle / jdbc / main”.
>将JDBC驱动程序jar(ojdbc6.jar)放在此目录中.
>创建模块配置文件module.xml：
示例Oracle JDBC驱动程序module.xml文件
<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="com.oracle">
<resources>
<resource-root path="ojdbc6.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
示例Oracle数据源配置
<datasources>
<datasource jndi-name="java:jboss/OracleDS" pool-name="OracleDS">
<connection-url>jdbc:oracle:thin:@localhost:1521:XE</connection-url>
<driver>oracle</driver>
<security>
<user-name>admin</user-name>
<password>admin</password>
</security>
<validation>
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker"/>
<validate-on-match>true</validate-on-match>
<background-validation>false</background-validation>
<stale-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker"/>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"/>
</validation>
</datasource>
<drivers>
<driver name="oracle" module="com.oracle">
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
管理CLI命令示例
可以使用以下管理CLI命令来实现此示例配置.
1#将Oracle JDBC驱动程序添加为核心模块.
模块添加–name = com.oracle –resources = / path / to / misc / jdbc_drivers / oracle / ojdbc7.jar –dependencies = javax.api,javax.transaction.api
2#注册Oracle JDBC驱动程序.
/ subsystem = datasources / jdbc-driver = oracle：add(驱动程序名称= oracle,驱动程序模块名称= com.oracle,driver-xa-datasource-class-name = oracle.jdbc.xa.client.OracleXADataSource)
3#添加Oracle数据源.
数据源添加–name = OracleDS –jndi名称= java：jboss / OracleDS-驱动程序名称= oracle-连接URL = jdbc：oracle：thin：@localhost：1521：XE-用户名= admin –password = admin –validate-on-match = true –background-validation = false –valid-connection-checker-class-name = org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker –exception-sorter-class-name = org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter –stale-connection-checker-class-name = org.jboss.jca.adapters.jdbc.extensions.oracle .OracleStaleConnectionChecker
